I recently botched a primer job with some 15mm science fiction figures, getting the notorious fuzzy finish. Acting on a tip, I went to the dollar store and picked up a bottle of LA’s Totally Awesome Cleaner. I poured it full strength into a tin on top of the figures.
Twelve hours later, the paint is just flaking away. I rinsed off a couple of figures as a test, and they’re good to go.
I will leave them in the tin for a few more hours just to be sure.
